Today, plastic processing equipment manufacturers are using the lower price resistance type Displacement sensor The displacement measurement and control, but this kind of equipment will appear serious wear and linear deviation phenomenon after using for a long time. The consequence to users is to spend a lot of money to repair and bear the serious loss of production stop. Germanjet engineers have developed 18 series of linear displacement measurement and control systems with the best application and cost saving. This new germanjet 18 series device has a round shell. such Displacement sensor When the measurement range is 50-1500 mm, the accuracy of repeated positioning is less than or equal to 20 mm.
So far, the cost of acquisition of non-contact control systems is still too high. Germanjet's 18 series solves this problem. As a replacement of resistance displacement sensor, germanjet company has introduced 18 series linear displacement sensor, which has the advantages of non-contact measurement and low purchase price.
The 18 series device with IP67 enclosure protection is placed in an anodized aluminum enclosed special-shaped shell. In this way, the system can be dustproof, waterproof and vibration and impact proof. The circular shell and its many advantages provide convenience and flexibility for installation. It can be fixed to any part of the machine. As long as the distance between the horizontal displacement sensor and the magnetic sensor is not exceeded, so long as the vertical distance between the sensor and the sensor is not exceeded, the possibility of damaging the sensor can be ruled out. The magnet can be placed with a vertical deviation of ± 5mm. Germanjet magnetostrictive displacement sensor It can be fixed with standard components commonly used in the market. Because the displacement sensor has large installation tolerance, it does not need time-consuming structural modification and precise adjustment. The ohmic holder with two positioning magnet position sensors is particularly cost-effective and can measure two axial motions with one measuring system without additional investment.
Use an M12 plug connection line for electrical connection. The working voltage of ohmic card holder is 24 V, with 10 V analog output or a P110 digital pulse interface for uninterrupted data transmission. It can match all the general processing cards of germanjet company and the control devices of various manufacturers, and can carry out 500 m signal security transmission. Enterprises using their own control and signal processing devices can also achieve resolution of the pulse interface analysis results.
There are also ohmic card holders with digital pulse interface / integrated protocol (DPI / IP), a protocol for direct data exchange between control devices and displacement sensors. The benefits of this protocol are: simple automatic parameterization, identification of damaged or replaced measurement systems, and improved machine security.
Germanjet's 19p displacement sensor can be used as a bus system. For example, there is no more than one model of the Profibus system. In this case, the bus conductor is separated from the supply voltage. Using Profibus and CANopen system, the speed data and diagnosis data of 4 positions can be transmitted to the control device at most. The resolution of position is 5mm and the speed is 0.1mm/s. In addition, by working with Wago, the germanjet ohmic card holder can be connected to all the bus systems common on the market. This connection is achieved through a 750 series terminal with an integrated ASIC unit for pulse interface and corresponding bus coupler.
